Fourier transform holography at the wavelength limit
, 2022 Paper DTh2E.4We present a table-top Fourier transform holography experiment that achieved a record-high resolution of 34 nm. By employing phase retrieval techniques, the resolution was improved to 23 nm (

Feed particle size evaluation: conventional approach versus digital holography based image analysis
Italian Journal of Animal Science, 2010 The aim of this study was to evaluate the application of image analysis approach based on digital holography in defining particle size in comparison with the sieve shaker method (sieving method) as reference method.

Journal of Mathematical Analysis and Applications, 1980 AbstractThe problem that is presented and investigated is a natural nonlinear extension of the following linear problem. Let H ⊕ H′ and K ⊕ K′ be two orthogonal Hilbert decompositions of a real Hilbert space X. Let P, P′, Q, Q′ and N′ be the operators of orthogonal projection of X onto H, H′, K, K′ and H′ ∩ K′ respectively.
